GASKET FOR RADIATOR GAPS.

Application filed August 11, 1924. Serial No; 731,280.

My present invention relates to radiator caps of the type adapted to be permanently locked to the threaded neck of a radiator and having a hinged cover adapted to be opened to permit the filling of the radiator and to be normally held in closed, steamtight relationship with respect to the'body of the cap.

The cap to which my invention is particularly adapted includes an outer body and an inner member, which may be called an insert or adapter, adapted to be screwed onto the radiator neck and to be locked to said outer body in such manner that the latter may be rotated without unscrewing the insert. 1

The invention has for a primary object the provision of a packing, or gasket, particularly adapted for use in aradiator cap construction of this character, though it will be evident, as the description progresses, that the form of gasket provided by the invention may also have valuable use in other connections. I

An important object of the invention is the provision of a packing, or gasket, which will be positively and firmly held in position of service and which will be unusually efifective in preventing the leakage of water or steam.

Another object of the invention is the provision of a reversible gasket of this character which is adapted to conform to the various parts of the cap construction with which it is associated, the parts being adapted to cooperate as well after being reversed as otherwise, and the gasket being thus adapted for long, as well as efficient service.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a-preferrcd embodiment thereof.

Referring to the drawings,

Figure 1 is a front elevation, partially broken away and shown in section, of a radiatorcap in which my invention is embodied;

gig. 2 is a perspective view of the gasket; an

Fig. 3 is a detail view, partially in section and partially in elevation, of the latter.

Upon said drawings, disclosing the best manner in which I have contemplated ap plying the principles of my invention, the reference character 11 indicates the body of the cap, which is provided wit-h extended arms 12 at theopposite sides thereof, terminating in round balls 13, of symmetrical form, the body 11 being adapted to be retatably locked to an insert or adapter 14, which is provided with screw threads 15 adapted to cooperate with the front of the filler neck of the radiator to hold the cap in place. Means (not shown) is preferably pro-' vided to lock the body 11 and insert- 14 together when said body is rotated in direction to screw the insert 14 onto the radiator neck, the body being permitted to turn freely upon the insert, however, when rotated in the opposite direction, to prevent removal of the cap after it has been positioned. A cover 16 is provided upon the body, being preferably hinged at the back and being provided with means to receive and support a motometer 17, which is adapted to be permanently locked thereto. 1

The gasket comprises a body 18, which is beveled in opposite directions on its inner side at 19 and 21 and has tin-outwardly extending flange 22. Said flange 22 is adapted to be clamped between an inclined top portion 23 on the insert 14 and an inwardly extending flange 24 on the upper part of the body 11, it being understood that these parts may be telescopically assembled and the looking elements thereof so arranged that-a tight fit of these parts against the gasket flange 22 may be provided.

The under surface of the cover 14 is beveled to cooperate with the beveled inner surface 19 or 21 :on the gasket 18, and it will thus be evident that when the cover is tightly closed, .a sealing contact throughout a considerable area is provided which will prevent the escape of wateror steam. The gasill ' render the same steam ket, obviously, may be reversed, the flange 22 being sufficiently flexible to extend in either direction to the inclined position of Fig. 1, and the outer portions of the body 18 being adapted to fit tightly against the inner wall of the insert 14 and the interior of the body flange 24;, respectively.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts, without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. In a radiator cap, the combination of an inner collar,'an. outer collar, a hinged cover on the outer collar, and a gasket clamped vertically between said inner and outer collars and having a part adapted to cooperate with said cover when closed to and water-tight.

2. In a radiator cap, the combination of an inner collar, an outer collar, a hinged cover on the outer collar, and a gasket clamped vertically between said inner and outer collars and having a part adapted to cooperate with said cover when closed to render the same steam and water-tight, said part being usable inreverse positions of the gasket.

3. In a radiator cap, the combination of an inner collar, an outer collar, av hinged cover on the outer collar, and a gasket clamped vertically between said inner and outer collars and having a part adapted to cooperate'with said cover when closed to render the same steam and water-tight, the under side of said cover being beveledand said, cooperating part on the gasket being correspondingly beveled to produce tight contact therewith. 7

4. In a radiatorcap, the combination of an inner collar adapted to be attached to the radiator neck, an outer collar assembled in non-separable relationship to said inner collar and having a substantially horizontal flange extending inwardly above the latter, a cover hinged to said outer collar, and a gasket having a peripheral portion clamped between the flange of the outer collar and the top of the inner collar and a portion adapted to cooperate with said hinged cover to form a steam-tight joint. therebetween when the latter is closed.

5. In a radiator cap, the combination of an innercollar adapted to be attached'to the radiator neck, an outer collar assembled in non-separable relationship to said inner collar and having a flange extending inwardly above the latter, a cover hinged to said outer collar and having a beveled part on the under side thereof, and a gasket having a peripheral portion clamped between the flange of the outer collar and the top of the inner collar, and a beveled portion adapted to cooperate with said hinged cover to form a steam-tight joint therebetween when the latter is closed.

6. In a radiator cap, the combination of an inner collar adapted to be attached to the radiator n eck, an outer collar assembled in non-separable relationship to said inner collar and having aflange extending inwardly above the latter, a cover hinged to said outer. collar and having a beveled part on the under side thereof, and a gasket having a peripheral portion clamped between the flange of the outer collar and the top ofthe inner collar and a beveled portion adapted to cooperate with said hinged cover to form a steam-tight joint therebetween when the latter is closed, said beveled portion of the gasket being beveled in both directions from a center line and thus usable in reverse positions. c

7 In a radiator Zcap, the combination of an inner collar, an outer collar, a hinged cover on'the outer collar, and a gasket ar ranged to provide a steam-tight seal with the cover when the latter is closed, said gasket being adapted to be forced tightly against the, inner wall of the inner collar by pressure of the cover in closing andhaving a laterally extending cushioning portion backing against a fixedpart of the cap.

8. Ina radiator cap, the combination of an inner collar, an outer. collar, a hinged cover on the outer collar and a gasket having a portion arranged above the top of the inner collar and beneath an inwardly ex: tending flange on the outer collar, said por tion. being restrained by the outer collar against radial expansion, and a geveled portion adapted to contact with the under side In a radiator cap, the combination of" an inner collar, an outer collar, a hinged cover on the outer collar, and a gasket arranged on the interior of the cap and having a beveledportion adapted to contact with a beveled part on the under. side of the cover to produce tight sealing engagement throughout a substantial area of contact, said gasket having a cushioning portion extending laterally from said beveled portion and backing against a fixed part of the cap.

10. In a radiator cap, the combination of an inner collar, an. outer collar, a hinged cover on the outer collar, and a gasket secured within the cap and having-a portion in closing and a cushioning portion extending laterally therefrom and adapted to receive a portion of the thrust produced by the closing of the cover.
